Progressive Outline to Decarbonize Buildings

By Jeff Ihnen Energy Rant No Comments

Two weeks ago, I described an array of district heating and cooling plants that serve medical, college, industrial, and even city-scale loads. Last week, I explained options to decarbonize district heating and cooling plants. Those options include converting systems from steam to hot water as equipment reaches the end of its useful life, heat recovery chillers, and, most importantly, energy efficiency in facilities and processes served. But before getting started on efficiency, I must add that there are also many barriers to shutting down a district steam plant and transitioning to distributed heating and cooling plants. First, there are loads other than space…

Decarbonizing District Steam and Chilled Water Plants

By Jeff Ihnen Energy Rant No Comments

Let's begin with Oxford Dictionary's definition of decarbonization. Noun: reduction or elimination of carbon dioxide emissions from a process such as manufacturing or the production of energy. Last week, I introduced central or district plants that serve multiple buildings with steam, chilled water, and, in many cases, electricity. District plants serve colleges, healthcare, manufacturing campuses, and, in some cases, entire sections of cities. This week, I describe issues and strategies to save energy and decarbonize these plants. As I learned early in my energy efficiency career, it is essential to understand the design logic behind the system before recommending modifications. Steam moves…

Decarbonization – An Introduction to District Plants

By Jeff Ihnen Energy Rant No Comments

I would like to see a poll of peoples’ suggestions for decarbonization. My guess is solar panels would be near the top; next, maybe an electric vehicle; after that, maybe electrified appliances and HVAC. Are any of these investments cost-effective? Keeping it simple, are the accrued savings over the life of the project or object more than the cost? It depends on the baseline alternative and various stackable incentives. Without guessing and getting into details, I believe consumer electrification and decarbonization are driven more by non-financial matters. What about commercial and industrial facilities? It gets decidedly more challenging because the…

Electric Vehicle Discoveries & Trajectories

The depth of decarbonization will ride the line where the net of cost and convenience meets that of conventional alternatives. Polling from the University of Chicago indicates 38% of Americans are willing to chip in one (1) dollar per month to fight climate change, down fourteen percentage points from 2021 (presumably, that 14% are willing to pay nothing now). Or, as one Wall Street Journal article noted in November, “Someone has to pay for it, and shareholders and consumers decided this year it wouldn’t be them.” For instance, I like to cut, split, stack, haul, and burn wood for heat. It must burn hot…

Decarbonize and Reduce Costs with Dynamic Pricing

By Jeff Ihnen Energy Rant No Comments

Market Prices Continuing from last week, how do we cost-effectively decarbonize the grid at a continental scale? Start with baseload nuclear power and, from there, load management. To achieve optimal load management to keep electricity costs low for customers, customers must see market prices in short-term forecasts, like weekly, day-ahead, or even near-real-time pricing. Tariffs, or rates today, are relics of the analog days when utilities deployed armies of people in pickup trucks to run around and manually read meters. When I was a kid, my dad tasked me with reading meters on building sites away from the home site.…

Dive Into Cement Manufacturing Emissions

By Jeff Ihnen Energy Rant No Comments

Over the years, I’ve seen numerous mentions of decarbonizing concrete or cement. Random articles describing the need and means to decarbonize cement include this McKinsey article, this DOE post, and this Canary Media article. Those don’t cut it for me. I set out to explore cement making and why it is so carbon-intensive. But first, some terminology review is advised to differentiate cement from concrete. Growing up, in college, and even post-college, we used the term cement synonymously with concrete. E.g., “cement hands” to describe a guy who couldn’t catch a basketball or football or “cement head” to tell civil engineers. Each of…

Electric Vehicle Plans With the End in Mind

By Jeff Ihnen Energy Rant No Comments

This week I’m repackaging recent news on electric vehicle (EV) developments – market, technical, and utility impacts. I like to look at scale (macro) rather than ubiquitous siloed micro thinking. Is it realistic to scale rare earth mineral mining, battery manufacturing, and battery disposal? What about charging logistics, third-world labor, and grid impacts? Breaking the Grid? Let’s start with the revelation that force, in the form of mandates, will break things. An aeronautical engineer’s piece in Energy Central, says EVs, at scale, will break the grid. He notes that the Biden regime is developing restrictions requiring the market share of…

Are You Serious About the Climate Apocalypse?

By Jeff Ihnen Energy Rant, Featured Energy Rant No Comments

Washington Post headline last week: “World is on brink of catastrophic warming, U.N. climate change report says.” Wolf! Wolf! People aren’t serious about decarb, and this post will prove it, but I provide ways to get it done. Is Solar Plus Storage Competitive? Solar is nice, but the numbers are ugly. If solar and storage with batteries were a serious contender for a clean energy grid, electric utilities would be soiling themselves because solar and batteries would put them out of business as customers would install their own and cut the cord. Let’s look at some basic arithmetic. Lazard pegs…

1,500 Pages of Deregulation

By Jeff Ihnen Energy Rant No Comments

Last week I mentioned genuine intelligence over artificial happy-talk intelligence. Want to know what the latter looks like? See this Forbes article in which data solves all problems, including heating and cooling buildings. “There is an opportunity to build the foundations of a long-term digital strategy for buildings in all industries, to achieve decarbonization goals, reduce energy use and running costs, and boost resiliency and competitiveness.” How many Btus of energy are in a terabyte anyway? Harnessing data, plus actionable analytics, which is rare, can help shave 10% or even 20% off energy costs. Still, it must be integrated with…

Decarb Warriors

By Jeff Ihnen Energy Rant No Comments

Last week I read a statement from a retail energy provider. It said, “100% green rates, always.” It doesn’t work that way. An aggregation of power sources, including renewable, nuclear, coal, and natural gas, are supplying the grid at any given time. The little electrons aren’t tagged by source and routed to any given customer(s). Second, even if that were impossible, er, I mean, possible, it’s shoving more hydrocarbon electricity onto someone else. In this way, it’s the same as the net zero con. Cheap but Unreliable Generating renewable power is easy and inexpensive, but as described in the net-zero…
